 a second body having one end connected to the other end of the first body and the other end that is inclined at a predetermined angle and is extended toward the glass diffuser plate; and 
 a third body having one end connecting to the other end of the second body and the other end that is extended to the outside in parallel to the horizontal portion and supports the glass diffuser plate. 
 
     
     
       7. The liquid crystal display of  claim 6 , wherein the printed circuit board does not protrude from a side of the liquid crystal display panel. 
     
     
       8. The liquid crystal display of  claim 6 , wherein the vertical portion of the cover bottom comprises:
 a fourth body having one end connected to one end of the horizontal portion and the other end extended toward the glass diffuser; 
 a fifth body having one end connected to the other end of the fourth body and the other end that is extended to support the glass diffuser plate and in parallel to the horizontal portion; and 
 a sixth body having one end connected to the other end of the fifth body and the other end that is inclined at a predetermined angle and is extended toward the horizontal portion of the cover bottom. 
 
     
     
       9. The liquid crystal display of  claim 8 , wherein a height from the horizontal portion to the third body is substantially the same as a height from the horizontal portion to the fifth body. 
     
     
       10. The liquid crystal display of  claim 8 , further comprising a reflective sheet accommodated in an inner space provided by the vertical portion and the horizontal portion of the cover bottom,
